so if we say: readelf -a /bin/bashĪll the contents in the binary file bash would be shown to us, also we could provide different flags for readelf to see all the sections and headers of an elf file separately, for example if we want to see only the elf header we say: readelf -h /bin/bashįor reading all the segments of the file: readelf -l /bin/bashįor reading all the sections of the file: readelf -S /bin/shīut again as summary, for reading a normal file like "hello.c" and a binary file like bash in path /bin/bash in linux we say: xxd hello. įor example if we want to see all the convert all the contents of a binary file(executable, shared libraries, object files) we say: hexdump binaryfilenameīut readelf is the best utility for analyzing elf(executable and linking format) files.
To see all the contents and codes in a binary file, we could use commands like readelf and objdump, hexdump. Let’s see an example to get the clarity on hexadecimal and binary number representation. Each block is replaced by the corresponding hex digit. To convert a file to its binary codes(hexadecimal representation) we say: xxd filename # To convert from binary to hex representation, the bit string id is grouped in blocks of 4-bits which are called as nibbles from the least significant side.
